NFPA 25 requires an internal inspection of sprinkler system piping at least once every 5 years to check for obstructions, corrosion, and other potential issues.

Local Law 58 of 2009 focuses on testing, maintenance, and reporting requirements for sprinkler systems. The installation of backflow prevention devices is not specifically addressed in this law.

NFPA 13 requires a minimum pressure of 20 psi at the most remote area of a sprinkler system to ensure adequate coverage and performance.

While important for overall fire safety, fire department response times are not part of the required records for sprinkler systems. The other options are mandatory records as per NFPA 25 and NYC Fire Code.

NFPA 13 requires that water be delivered to the inspector's test connection within 60 seconds for dry pipe systems to ensure timely activation in case of fire.

While pipe wall thickness testing is important for system integrity, it is not specifically a reason for conducting an obstruction investigation. The other options are valid reasons as per NFPA 25.

NFPA 13 requires a minimum water supply duration of 90 minutes for Extra Hazard occupancies to ensure adequate fire suppression capabilities.

Standard upright sprinklers contain water in the piping and are not suitable for freezing areas. The other options are designed to prevent freezing in cold environments.

NFPA 25 requires that dry pipe valves undergo a full trip test at least once every 3 years to ensure proper operation and to identify any potential issues.

While periodic visual inspection is important, it is not considered a valid method of continuous sprinkler system supervision. The other options provide constant monitoring of the system's status.

NFPA 13 requires a minimum clearance of 18 inches between sprinkler deflectors and the top of storage in storage occupancies to ensure proper sprinkler activation and coverage.

Electrostatic generators are not used as water supplies for sprinkler systems. The common types include city water mains, gravity tanks, pressure tanks, and fire pumps.

According to NFPA 25 and NYC Fire Code, waterflow alarm devices must be inspected monthly to ensure proper operation and signaling.

While building owners are responsible for maintaining, inspecting, and testing existing sprinkler systems, the design and installation of new systems are typically performed by licensed professionals and contractors, not the building owner.
